如何通过 AWS CDK CfnResource 访问标签值？

Question

While experimenting with AWS CDK for Python I do not seem to be able to extract a tag value from a CfnResource.

Example VPC (I understand that the core focus is on ec2.VPC, but it is just an experiment):

vpc = ec2.CfnVPC(stack, 
              id = "vpc-id",
              cidr_block="10.1.0.0/16",
              enable_dns_hostnames=True,
              enable_dns_support=True,
              tags=[core.CfnTag(key="Name", value="vpc-name")])

How can I get to the value of the "Name" tag through CfnVPC construct?

I have tried vpc.tags but it seems to give me TagManager that does not expose a get tag interface.

What am I missing?

I can created a tagged VPC using the AWS CDK 1.25.0 as below

tagName = core.CfnTag(key="Name", value="Resource Name")
tagEnv = core.CfnTag(key="environment", value="production")
tagArr = [tagName, tagEnv]

vpc = ec2.CfnVPC(self, "test", cidr_block="192.168.5.0/24", tags=tagArr)
